Scrape ResearchGate Profile Page in Python

What will be scraped

Prerequisites

Basic knowledge scraping with CSS selectors

CSS selectors declare which part of the markup a style applies to thus allowing to extract of data from matching tags and attributes.

If you haven't scraped with CSS selectors, there's a dedicated blog post of mine about how to use CSS selectors when web-scraping that covers what it is, pros and cons, and why they're matter from a web-scraping perspective and show the most common approaches of using CSS selectors when web scraping.

Reduce the chance of being blocked

There's a chance that a request might be blocked. Have a look at how to reduce the chance of being blocked while web-scraping, there are eleven methods to bypass blocks from most websites.

Install libraries:

pip install parsel playwright

scrape_researchgate_profile(profile="Agnis-Stibe")

Code explanation

Import libraries:

from parsel import Selector
from playwright.sync_api import sync_playwright
import re, json, time

Code	Explanation
`parsel`	to parse HTML/XML documents. Supports XPath.
`playwright`	to render the page with a browser instance.
`re`	to match parts of the data with regular expression.
`json`	to convert Python dictionary to JSON string.

Define a function:

def scrape_researchgate_profile(profile: str):
    # ...

Code	Explanation
`profile: str`	to tell Python that `profile` should be an `str`.

Open a playwright with a context manager:

with sync_playwright() as p:
    # ...

Define the structure of the extracted data:

profile_data = {
    "basic_info": {},
    "about": {},
    "co_authors": [],
    "publications": [],
}

Lunch a browser instance, open and goto the page and pass response to HTML/XML parser:

browser = p.chromium.launch(headless=True, slow_mo=50)
page = browser.new_page(user_agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.64 Safari/537.36")
page.goto(f"https://www.researchgate.net/profile/{profile}")
selector = Selector(text=page.content())

Code	Explanation
`p.chromium.launch()`	to launch Chromium browser instance.
`headless`	to explicitly tell `playwright` to run in headless mode even though it's a default value.
`slow_mo`	to tell `playwright` to slow down execution.
`browser.new_page()`	to open new page. `user_agent` is used to act a real user makes a request from the browser. If not used, it will default to `playwright` value which is `None`. Check what's your user-agent.

Update basic_info dictionary key, create new keys, and assing extracted data:

profile_data["basic_info"]["name"] = selector.css(".nova-legacy-e-text.nova-legacy-e-text--size-xxl::text").get()
profile_data["basic_info"]["institution"] = selector.css(".nova-legacy-v-institution-item__stack-item a::text").get()
profile_data["basic_info"]["department"] = selector.css(".nova-legacy-e-list__item.nova-legacy-v-institution-item__meta-data-item:nth-child(1)").xpath("normalize-space()").get()
profile_data["basic_info"]["current_position"] = selector.css(".nova-legacy-e-list__item.nova-legacy-v-institution-item__info-section-list-item").xpath("normalize-space()").get()
profile_data["basic_info"]["lab"] = selector.css(".nova-legacy-o-stack__item .nova-legacy-e-link--theme-bare b::text").get()

Code	Explanation
`profile_data["basic_info"]["name"]`	to access earlier created `basic_info` key, and then create a new `["name"]` key, and assign extracted data.
`css()`	to parse data from the passed CSS selector(s). Every CSS query traslates to XPath using `csselect` package under the hood.
`::text`	to extract textual data from the node.
`get()`	to get actual data from a matched node
`xpath("normalize-space()")`	to parse blank text node as well. By default, blank text node is be skipped by XPath.

Update about dictionary key, create new keys, and assing extracted data:

profile_data["about"]["number_of_publications"] = re.search(r"\d+", selector.css(".nova-legacy-c-card__body .nova-legacy-o-grid__column:nth-child(1)").xpath("normalize-space()").get()).group()
profile_data["about"]["reads"] = re.search(r"\d+", selector.css(".nova-legacy-c-card__body .nova-legacy-o-grid__column:nth-child(2)").xpath("normalize-space()").get()).group()
profile_data["about"]["citations"] = re.search(r"\d+", selector.css(".nova-legacy-c-card__body .nova-legacy-o-grid__column:nth-child(3)").xpath("normalize-space()").get()).group()
profile_data["about"]["introduction"] = selector.css(".nova-legacy-o-stack__item .Linkify").xpath("normalize-space()").get()
profile_data["about"]["skills"] = selector.css(".nova-legacy-l-flex__item .nova-legacy-e-badge ::text").getall()

Code	Explanation
`profile_data["basic_info"]["name"]`	to access earlier created `basic_info` key, and then create a new `["name"]` key, and assign extracted data.
`re.search(r"\d+", <returned_data_from_parsel>).group()`	to extract digit data via `re.search()` regular expression `\d+` from the returned string. `group()` is to extract substring that was matched by the regular expression.
`css()`	to parse data from the passed CSS selector(s). Every CSS query traslates to XPath using `csselect` package under the hood.
`::text`	to extract textual data from the node.
`get()`/`getall()`	to get actual data from a matched node, or to get a `list` of matched data from nodes.
`xpath("normalize-space()")`	to parse blank text node as well. By default, blank text node is be skipped by XPath.

Iterate over co-authors and extract individual co-author, and append to the temporary list:

for co_author in selector.css(".nova-legacy-c-card--spacing-xl .nova-legacy-c-card__body--spacing-inherit .nova-legacy-v-person-list-item"):
    profile_data["co_authors"].append({
        "name": co_author.css(".nova-legacy-v-person-list-item__align-content .nova-legacy-e-link::text").get(),
        "link": co_author.css(".nova-legacy-l-flex__item a::attr(href)").get(),
        "avatar": co_author.css(".nova-legacy-l-flex__item .lite-page-avatar img::attr(data-src)").get(),
        "current_institution": co_author.css(".nova-legacy-v-person-list-item__align-content li").xpath("normalize-space()").get()
    })

Code	Explanation
`::attr(attribute)`	to extract attribute data from the node.

Next is to iterate over all publications and extract individual publications, and append to a temporary list:

for publication in selector.css("#publications+ .nova-legacy-c-card--elevation-1-above .nova-legacy-o-stack__item"):
    profile_data["publications"].append({
        "title": publication.css(".nova-legacy-v-publication-item__title .nova-legacy-e-link--theme-bare::text").get(),
        "date_published": publication.css(".nova-legacy-v-publication-item__meta-data-item span::text").get(),
        "authors": publication.css(".nova-legacy-v-person-inline-item__fullname::text").getall(),
        "publication_type": publication.css(".nova-legacy-e-badge--theme-solid::text").get(),
        "description": publication.css(".nova-legacy-v-publication-item__description::text").get(),
        "publication_link": publication.css(".nova-legacy-c-button-group__item .nova-legacy-c-button::attr(href)").get(),
    })

Print extracted data, and close browser instance:

print(json.dumps(profile_data, indent=2, ensure_ascii=False))

browser.close()


# call function. "profiles" could be a list of authors.
# author name should be with a "-", otherwise ResearchGate doesn't recognize it.
